Then, the two of them passed Li Chengqian and ran directly towards Chang'an City.
It had just snowed heavily yesterday. The two of them were running on the road. They ran wildly for a certain distance, then stopped and slid forward.
In this way, when they were tired from running, the two of them stood by the roadside, slowly waited for Li Chengqian's carriage to come, and got on it.
…
Inside Chang'an City.
After hearing Li Wei's order, Zheng Ye, the eunuch of the Young Mansion, ordered the craftsmen to start forging the large iron furnace and ran to the palace with a face full of anxiety.
Twenty large iron stoves must be matched with a sixty-foot iron stove, which requires at least 2,400 kilograms of pig iron.
However, although the Shaofu Superintendent was in charge of all kinds of craftsmanship, there was only a surplus of two thousand kilograms of pig iron in the warehouse, which was not enough to forge so many iron furnaces.
"Not enough pig iron?"
In Liangyi Hall, after listening to Zheng Ye's report, Li Shimin looked surprised.
"There are only twenty large iron stoves, and a young governor doesn't have so much pig iron?"
"Your Majesty, I dare not lie. There are indeed only two thousand kilograms of pig iron in the Young Master's prison!"
Zheng Ye quickly replied.
"Two thousand kilograms of pig iron is not enough?"
Li Shimin's eyes widened, and then he couldn't help but think of something, and asked quickly: "Zheng Ye, how much pig iron is needed to forge a large iron furnace?"
"Return to Your Majesty, one hundred pounds of pig iron!"
Hearing Li Shimin ask for the reason, Zheng Ye felt relieved and continued: "Your Majesty, the three-foot iron cylinder equipped with each large iron stove also requires twenty kilograms of pig iron!"
"hiss……"
Hearing this, Li Shimin looked shocked and took a deep breath, his eyes filled with distress.
"Twenty iron stoves require 2,400 kilograms of pig iron!"
"Your Majesty is wise!"
Zheng Ye cupped his hands and replied.
In my heart, I finally breathed a sigh of relief.
Now, Your Majesty will probably not consume so much pig iron to forge those twenty useless iron stoves!
"But the Supreme Emperor asked me to forge ten large iron stoves for him yesterday!"
But he didn't want to, Li Shimin frowned again and said softly.
Hearing this, Zheng Ye shuddered subconsciously.
The Supreme Emperor?
"Your Majesty, His Royal Highness the Crown Prince wishes to see you!"
Just when Zheng Ye and Li Shimin were looking embarrassed, a chamberlain walked in from outside the palace and reported.
"Gao Ming is back?"
Li Shimin was stunned for a moment, and then said quickly, "Let him in quickly!"
After a while, Li Chengqian hurried in.
"My son has met my father!"
"Gao Ming, shouldn't you be in Lijiazhuang at this time? Why did you come back in such a hurry?" Li Shimin asked directly.
"Go back to my father, I have something urgent to report!"
Li Chengqian glanced curiously at the Young Mansion Supervisor Zheng Ye who had a bitter look on his face next to him, and then said to Li Shimin.
"Your Majesty, Your Highness, I'll take my leave first!"
During this period, Prince Li Chengqian and the Supreme Emperor went to Lijiazhuang in the south every day, and most of the ministers and dignitaries in Chang'an City knew about it.
Therefore, seeing Li Chengqian so anxious, Zheng Ye subconsciously wanted to run away.
However, I haven't taken a few steps yet.
Then I heard Li Chengqian say: "Father, this matter is about the method of making iron!"
Suddenly, Zheng Ye seemed to have roots under his feet and could no longer walk.
By coincidence, Li Shimin also said: "Since it is about the method of making iron, Zheng Jiancheng might as well listen to it!"
"Yes, Your Majesty!"
So, Zheng Ye quickly walked back.
"Father, Master and Grandpa Huang would like to ask Father to forge two hundred and thirty large iron stoves and place them in the glass greenhouse of Lijiazhuang!"
Li Chengqian smiled at Zheng Ye and said loudly.
"Two hundred and thirty iron stoves!"
Zheng Ye felt his eyes go dark, his head was buzzing, and he wanted to faint.
Li Shimin was also surprised and hurriedly asked Li Chengqian: "Why do you suddenly need so many iron stoves?"
"Father, the weather is too cold. Only by putting an iron stove in each greenhouse can we keep the greenhouses warm!"
Li Chengqian replied slowly.
Hearing this, Li Shimin's eyelids twitched and he took a deep breath.
"Gao Ming, do you know how many kilograms of pig iron are needed to forge such a large number of iron stoves?"
"It will cost 30,000 kilograms to return to my father!"
Li Chengqian replied.
"Thirty thousand kilograms of pig iron!"
After hearing this, Li Shimin couldn't help but stare at Li Chengqian closely, "As the prince, do you know how many soldiers can be equipped with these pig irons if they are used to forge armor?"
"Go back to my father, I will naturally know about this!"
Li Chengqian smiled softly and continued: "It's just that my father, Master said that after the iron furnace is forged, he will return one hundred thousand kilograms of pig iron to you!"
"One hundred thousand catties?"
In an instant, Li Shimin and Zheng Ye couldn't help but stare at Li Chengqian with wide eyes.
"Prince, do you know that there is no joke before you? One hundred thousand kilograms of pig iron is no joke!"
"Father, I have a method of smelting iron. In less than an hour, I smelted two hundred kilograms of pig iron. Because of this, the emperor allowed me to come and report this matter to my father!"
Li Chengqian was still smiling.
"An hour?"
Li Shimin stood up directly, startling Li Chengqian.
Zheng Ye on the side also trembled, and then his face was full of excitement.
"Your Highness, are you telling the truth?"
"Zheng Jiancheng, the two hundred kilograms of pig iron were made by me and my master together. Grandpa Huang also witnessed this with his own eyes!"
Li Chengqian raised his head and replied.
"I didn't expect there to be such a magical method of making iron?"
As the Chief Supervisor of the Young Mansion, Zheng Ye naturally understood how long it would take and how much manpower and material resources it would take to smelt two hundred kilograms of pig iron according to the iron-making method currently mastered by the imperial court.
Therefore, after listening to Li Chengqian's words, his face was even more shocked.
"Your Majesty, the imperial court must obtain this kind of iron-smelting technique!" Zheng Ye quickly said to Li Shimin.
By this time, Li Shimin had already walked to the back of the palace.
"Li Wei, follow me to Lijiazhuang!"
"yes!"
After a while, Li Shimin led Li Wei, followed by Li Chengqian and Zheng Ye, and hurried out of the palace gate.
However, before taking a few steps, I heard familiar screams.
Before Li Shimin could speak, the carriage had stopped.
"Your Majesty, Duke Cheng Guo and Prince Hejian are waiting in front!" Li Wei reported.
"Cheng Zhijie and Li Xiaogong?"
In the car, Li Shimin looked surprised.
"It's Cheng Chusi and Li Chongyi!"
At the same time, Li Chengqian's expression also changed slightly, and he finally remembered that Cheng Chusi and Li Chongyi had come back with him.
Immediately, he quickly followed Li Shimin and got out of the car.
He looked forward, his face suddenly full of weirdness.
Cheng Chusi and Li Chongyi, their bodies were densely covered with footprints, their faces were hunched and full of depression.
"Your Majesty... Hey, His Royal Highness the Crown Prince is back too?"
When he saw Li Shimin, Li Chengqian, Cheng Zhijie and Li Xiaogong coming, his expression changed slightly.
However, it soon returned to normal.
"Zhijie, Xiaogong, what are you two doing?" Li Shimin asked curiously.
"Back to Your Majesty, I, Old Cheng, was preparing to go drinking with Prince Hejian. Unexpectedly, I saw these two bastards outside the palace gate. They were so sneaky that I thought they had sneaked back..."
Cheng Zhijie cupped his hands towards Li Shimin and Li Chengqian and said.
After listening, Li Shimin looked strange.
"Your Majesty, are you going to Lijiazhuang with the prince?" Cheng Zhijie asked.
"Um!"
Li Shimin nodded slightly, "Xuanba has a magical iron-making method that can produce two hundred kilograms of pig iron in one hour. You come with me!"
"Yes, Your Majesty!"
After hearing this, Cheng Zhijie and Li Xiaogong's expressions changed greatly, and they nodded quickly.
